conf/ucm: Add chtrt5645-mono-speaker-analog-mic configuration

Add a configuration for Cherry Trail boards which use a rt5645 codec
connected to a mono speaker and with an analog mic on IN2N + IN2P.

The chtrt5645-mono-speaker-analog-mic/HiFi.conf for this is based on the
latest version from https://github.com/plbossart/UCM/tree/master/chtrt5645
with all the unused input options removed and some changes made to make
the analog mic work.

This commit also adds 2 ucm dirs with the longname of 2 boards known to use
this setup, which simply contain a symlink to the generic
chtrt5645-mono-speaker-analog-mic entry.
